Even if only a few copies hit high-value cards, this adds up quickly and can close games before your opponent has a chance to respond
What some players missed was that this card was being a bit more mischievous than was obvious at first glance
Anyways, that card itself: it enables cast-from-exile by giving you a repeatable impulse two, while also enabling cast-from-anywhere-that-isnt-your-hand synergies with Retrace
For the time being it doesn't solve the Vivi problem, but if that eats a ban in November as expected, prowess will still be a thing
Ideal for Draft, Sealed events, and building custom Constructed decks
While Opposition Agent was clearly intended as a tool to fight against higher power decks, it also simultaneously feels like a Stax card (a strategy intended to deny your opponents resources, primarily through mana disruption), a counterspell, and a Word of Command all wrapped up in a 3 mana package, and its impact has reached far beyond the intended purpose
